Native to northeast India, China, and Southeast Asia, Glaucous Climbing Bauhinia is a large shrub or vine that can grow to heights of 5-10 feet. This woody climber can be grown in full sun or in semi-shade and will thrive in warm climates, USDA Zones 9-11, but is cold hardy to temperatures in the 30s F for a short time. It will also tolerate regular and moderate water.
The plant produces white to off-white blossoms that attract butterflies and hummingbirds. The flowers, which are clustered in corymb-like clusters, have five spoon-shaped petals with three curved upward stamens. After the flowers die back, the plant produces a non-bursting pod.
Bauhinia polysperma is relatively easy to care for and propagate. It can be grown in a pot in cold regions, as long as extreme cold temperatures can be avoided. It requires regular pruning and trimming to prevent excessive growth and should be watered at least once a week. To promote healthy blooms, fertilizer should be applied every two to three months. For best results, it should be planted in a rich, well-draining soil and sheltered from damaging winds.
